Magnetic field around magnet The space where the magnetic force of the magnet acts is called a ‘magnetic field.’ The direction of the magnetic field is determined in the direction indicated by the N pole of the magnetic needle placed … more
This simulation analyzes the sound around you and displays it as a spectrum. The simulation works by recognizing the surrounding sounds. In the case of PC, please grant permission to use the microphone. Voice data is not stored on servers, … more
Iris muscles In the iris, the ‘Iris sphincter muscle’ constricts the pupil, and the ‘Iris dilator muscle’ enlarges the pupil. Both muscles work in reverse, controlling the size of the pupil. Ciliary body connected to the lens The lens of … more
The fluid in the beaker is water, and its density is assumed to be 1 g/mL. The volume of the object is assumed to be 100 mL. Buoyancy When we wear a life jacket, our bodies float on the water … more
Why is the submerged volume important to understand buoyancy? It is so famous that the 3rd-century Greek philosopher Archimedes shouted “Eureka!” and ran out of the bathhouse naked. （What did Archimedes find out? – Quotations from middle school science textbooks） … more
It is an optical experiment simulator consisting of a slit laser, lenses, and mirrors of various shapes. You can experiment by dragging the tool you want. Slit lasers are rotatable. Try dragging the red icon behind the laser. You can … more
This simulation allows you to measure speed as a function of fall height. Free fall movement All objects on Earth are affected by gravity. If there were no friction with air, the speed of any object would increase by 9.8 … more
Same Circuit In an electric circuit, voltage occurs at both ends of the cell. The place where this voltage is released is called ‘load’. In typical textbooks, ‘load’ is often replaced by a light bulb or resistor. Since a typical … more
